Abstract

The invention relates to the field of refrigeration, in particular to a precise temperature control cooling device. The precise temperature control cooling device comprises a condenser, an evaporator provided with a temperature sensing probe C and a compressor, wherein the evaporator is connected with the compressor, an intercept solenoid valve and a liquid storage device are arranged between the evaporator and the compressor in sequence, a condenser and a filter are arranged between the compressor and the evaporator in sequence, a loop is formed by the condenser, the evaporator and the compressor, and a sensing member controlling a fan on the condenser to be turned on and turned off is arranged on the loop. The precise temperature control cooling device has the advantages that refrigerants are stored, and the cooling system is made to be more stable; refrigerant loss caused by tiny leakage of refrigerating pipelines is corrected; in a low-temperature environment, the impact on the compressor by the refrigerants is relieved, and the compressor is protected.

Description

technical field [0001] The invention relates to the field of refrigeration, in particular to a precise temperature control refrigeration device. Background technique [0002] Refrigeration devices are widely used, but the compressors are frequently started and stopped in use at present, which causes damage to the compressors and greatly shortens the service life of the compressors. Contents of the invention [0003] In order to solve the above-mentioned technical problem of frequent start and stop of the compressor, the present invention provides a refrigeration device with precise temperature control. [0004] Technical scheme of the present invention is as follows: [0005] A precise temperature-controlled refrigeration device, comprising a condenser, an evaporator provided with a temperature sensing probe C, and a compressor, the evaporator is connected to the compressor, and an intercepting solenoid valve and A liquid accumulator, a condenser and a filter are sequent...
